when i was wheeling today and i had the rear right tire and the front left tire in the air and i had it in 4 hi they just spun but then i put it in 4 lo and i watched the rear right tire on video after this and it looks like i would have a limited slip because the wheel wasnt spinning when i was applying the gas it slowy turned and so did the wheel on the ground could it just be that it was in 4 lo or is their some kind of limited slip in the rear end its no bigge but i was wondering this since i got home

I have a similar question, lets hope Phantum or somebody pops in to give us the truth.

On my '90, I am about to buy lockers, question is this...How do I tell whether or not I have factory limited slip. Open diff lockers are different than limited slip lockers, so I need a foolproof way of knowing before I buy.

The easiest way to tell if it has a limited slip or not is to pop off the diff cover and look....if you can see spider gears in the carrier (you might have to rotate it a little), it's an open axle._________________97 XJ Sport with a bunch of stuff

okay so it might have come with a limited slip from the factory
one thing tho this is the only time i have seen it work when i got stuck in the mud one time i had one rear tire on dry pavement and i think it was in 4lo but not sure it could have been 4 hi but i know it was in 4 and my freind was out side and he said the tire just spun and didnt do any thing could it only show it in 4 lo or would it show it all the time if it was a limited slip??

A limited slip is just that...only some of the power will go to the wheel that needs it. The majority of the power will go to the wheel with no traction. On an open diff, all the power will go to the wheel with no traction.

As far as the wheels spinning fast in 4hi and slow in 4lo, remember...when you're in 4lo you have reduced gearing, so the wheel will spin slowly._________________97 XJ Sport with a bunch of stuff

im just going to have to jack the rear end up and check it out does anyone have pointers when doing this and what i will need
did 90 cherokee lardeo's even have a limited slip or does anyone know??
thx for the help

The higher trim packages might have had an LSD as standard equipment (key word, "might"). So if it's a Limited or a Sport (the 2 highest packages for that year), it's a good bet it has one. The only way to really tell is to open it up and look._________________97 XJ Sport with a bunch of stuff

It should have a tag on the diff cover, but that one usually only tells you the ratio. Plus a lot of times, that tag doesn't make it back on after the gear oil is changed...especially if a shop does it. My old 8.25 also had a paper tag around one of the axle tubes..that thing lasted long.

LSD's should not make noise. When they chatter like that it usually indicates some sort of problem. To little gear oil, contaminated gear oil (usually water), to little friction modifier or worn clutch plates/discs inside the LSD are the most common causes._________________97 XJ Sport with a bunch of stuff

jack up the rear axle of your jeep and then spin one tire. if the tire on the other end of that axle spins the same way - full locker. if it spins the opposite way - limited slip. if just sits there like a garden shrub - open differential.
